Compare peptide prices in the US

The peptides most stores serving the US list in USD: each page compares their prices per mg, stock and where they ship from.

Popular comparisons in the US

Stores based in the US that sell the most of the same peptides, side by side.

Monthly market report: who sells to the US, how many state third-party testing against how many we have checked, and USD prices per mg. Read the October 2026 report on the US

Buying research peptides in the US

Suppliers appear here because they are based in the US or state that they ship there. Prices are compared in USD only, never converted from other currencies, so the figures reflect what buyers in the US actually pay. Rules on buying, importing and possessing research peptides are set nationally, and the regulator in United States is the U.S. Food and Drug Administration (FDA): our page on whether peptides are legal in the US summarises them, with links to the sources.

To compare prices for one peptide in USD, go straight to BPC-157, Retatrutide, Tirzepatide, Semaglutide, Tesamorelin, GHK-Cu, Ipamorelin or Sermorelin. Before ordering from a supplier you have not used, run through our checklist for spotting an unreliable supplier, and check whether it publishes independent test results. The best-rated and fastest delivery rankings cover every region.
